Each conduit conveys approximately 100 MGD of raw water. The first conduit is commonly known as the “Old Conduit” while the second conduit is known as the “New Conduit”. The Old Conduit was constructed in the 1850s and is a circular conduit with an inside diameter that varies between 8 to 10 feet. The conduit is constructed of mostly of brick, stone, and mortar.  There are several sections that have been previously lined with shotcrete. There are other sections that were tunneled through rock and have been lined with cast-in-place concrete. The entire conduit is a permit-required confined space. The Old Conduit is an underground structure which passes through properties of the U.S. Government (including the US Army Corps of Engineers, the National Park Service, and other Agencies) and Montgomery County, Maryland.
